how to install hp deskjet 920c printer?
I was trying to install this printer, but the macbook doesn't take the software
MacBook Pro, Mac OS X (10.5), install printers
Is this what you're trying to install? This is the latest Mac driver for the 920C. Note that it was last updated in 2007 for OS X 10.5, and there may be no version of it that's compatible with OS X 10.6 or later. If that's the case, you may need to replace the 920C with a more modern printer.
